This document lists the MIGraphX driver commands along with the eligible options.
read#
Loads and prints input graph.
compile#
Compiles and prints input graph.
run#
Loads and prints input graph.
perf#
Compiles and runs input graph then prints performance report.
- --iterations, -n [unsigned int]#
Sets number of iterations to run for perf report (Default: 100)
verify#
Runs reference and CPU or GPU implementations and checks outputs for consistency.
- --rms-tol [double]#
Sets tolerance for RMS error (Default: 0.001)
- --atol [double]#
Sets tolerance for elementwise absolute difference (Default: 0.001)
- --rtol [double]#
Sets tolerance for elementwise relative difference (Default: 0.001)
- -i, --per-instruction#
Verifies each instruction
- -r, --reduce#
Reduces program and verifies
- --ref-use-double#
Converts floating point values to double for the ref target
roctx#
roctx provides marker information for each operation which allows MIGraphX to be used with rocprof for performance analysis.
This allows you to get GPU-level kernel timing information.
Here is how you can use roctx combined with rocprof for tracing:
/opt/rocm/bin/rocprof --hip-trace --roctx-trace --flush-rate 1ms --timestamp on -d <OUTPUT_PATH> --obj-tracking on /opt/rocm/bin/migraphx-driver roctx <ONNX_FILE> <MIGRAPHX_OPTIONS>
Running rocprof generates trace information for HIP, HCC and ROCTX in separate .txt files.
To understand the interactions between API calls, utilize the roctx.py helper script.
